Right now codes are season ticket account numbers only so I doubt you will get those. Other presales start tommorow.
As for the prices it is way too much for the cubs and opening day. Those prices are a joke but all other games are fairly cheap. I dont mind paying extra for one game to pay a lot less for all the other games. Elvis night I got 20 upper deck corner tickets for 140. Figured it would be a fun cheap group outing.

You can usually get better seats if you call a rep for group outings than buying them online.

Just did a look see with a code that was emailed to me from the Sox and there isn't much available. I even tried looking at an average game in June, but they wanted $70 for a lower box seat (not in "Platnum" area).

It's more convenient and CHEAPER to go on secondary sites. That is my plan for the opener. Congrats to you that were able to find good seats on the pre-sale!

I'm not sure what we can and can't discuss regarding the secondary sites, but the math is simple. As a buyer, I am going to go where the cost is the lowest. I have no doubt tickets, from lowers behind the plate to the upper deck, will be cheaper on the secondary market (will a little patience). I see no need to buy any game but opening day when tickets "officially" go on sale from the White Sox and Ticketmaster.

Not necessarily. The Sunday games in the bleachers plus the corner seats in both the upper and lower deck are going to be cheaper now than stubhub, due to Stubhub's fees.
